.TH CURLOPT_SSL_VERIFYPEER 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_SSL_VERIFYPEER \- verify the peer's SSL certificate
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYPEER, long verify);
.SH DESCRIPTION
Pass a long as parameter to enable or disable.
This option determines whether curl verifies the authenticity of the peer's
certificate. A value of 1 means curl verifies; 0 (zero) means it doesn't.
When negotiating a TLS or SSL connection, the server sends a certificate
indicating its identity. Curl verifies whether the certificate is authentic,
i.e. that you can trust that the server is who the certificate says it is.
This trust is based on a chain of digital signatures, rooted in certification
authority (CA) certificates you supply. curl uses a default bundle of CA
certificates (the path for that is determined at build time) and you can
specify alternate certificates with the \fICURLOPT_CAINFO(3)\fP option or the
\fICURLOPT_CAPATH(3)\fP option.
When \fICURLOPT_SSL_VERIFYPEER(3)\fP is enabled, and the verification fails to
prove that the certificate is authentic, the connection fails. When the
option is zero, the peer certificate verification succeeds regardless.
Authenticating the certificate is not enough to be sure about the server. You
typically also want to ensure that the server is the server you mean to be
talking to. Use \fICURLOPT_SSL_VERIFYHOST(3)\fP for that. The check that the
host name in the certificate is valid for the host name you're connecting to
is done independently of the \fICURLOPT_SSL_VERIFYPEER(3)\fP option.
WARNING: disabling verification of the certificate allows bad guys to
man-in-the-middle the communication without you knowing it. Disabling
verification makes the communication insecure. Just having encryption on a
transfer is not enough as you cannot be sure that you are communicating with
the correct end-point.
.SH DEFAULT
By default, curl assumes a value of 1.
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Set the default value: strict certificate check please */
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 1L);
curl_easy_perform(curl);
}
.fi
.SH AVAILABILITY
If built TLS enabled.
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
.SH "SEE ALSO"
.BR CURLOPT_SSL_VERIFYHOST "(3), "
